Meet Tenney: a ratio-first tuner and lattice for musicians who work in just intonation.
SEE INTERVALS INTUITIVELY
• Live pitch readout with pro-grade metrics and complications
• ± cents vs 12-TET and live Hertz
• Confidence readout to judge stability
• Adjustable root (e.g., 415 or 440 Hz) and prime-limit
EXPLORE a LIVE LATTICE
• 3×5 plane with pinch-to-zoom and smooth panning
• Tap to focus any node: p/q, ±¢ vs ET, and Hz at a glance
• Prime-overlay chips (7, 11, and beyond) to reveal higher-prime families
• Axis Shift ribbon (±3/5/7/11) to slide the lattice musically
MADE FOR THE WAY JI MUSICIANS THINK
• Ratio-centric labels with proper oddization
• Prime-limit control (3/5/7/11/13+)
• Strictness options for detection behavior (Loose / Performance / Strict)
• Designed to feel immediate, informative, and stage-safe
THOUGHTFUL BY DEFAULT
• Works offline; no accounts, no ads
• Light and Dark modes, portrait and landscape
• Fast, fluid UI with Apple’s latest glass effects where available
WHAT’S IN THIS VERSION
• Core tuner with ratio labels, cents vs ET, and confidence
• Lattice v0.3: explore, overlay chips, axis shifts, selection tray
• Practice timer and root-following test tone
WHO IT’S FOR
• Performers and composers working in just intonation
• Ear-training, rehearsal, and structural exploration of JI spaces
• Anyone curious about harmonic relationships beyond 12-TET
